| | | -- SWITCHING STATION |
| | | -- The switching station is the center of all power distribution on an electric network. |
| | | -- The station will collect all produced power from producers (PR) and batteries (BA) |
| | | -- and distribute it to receivers (RE) and depleted batteries (BA). |
| | | -- |
| | | -- The station collects power from sources (PR), distributes it to sinks (RE), |
| | | -- and uses the excess/shortfall to charge and discharge batteries (BA). |
| | | -- |
| | | -- For now, all supply and demand values are expressed in kW. |
| | | -- |
| | | -- It works like this: |
| | | -- All PR,BA,RE nodes are indexed and tagged with the switching station. |
